Development of Vibrational Rate Sensor and Navigation System 870215

We have developed a navigational system with which the motor vehicle travel route is drawn by a vibration-type rate sensor and a distance sensor, then compared with digital map data and corrected. [1] * [2]
It has been verified from numerous field tests that the use of the system being presented here allows a map to be traced. Since this system is a self-contained navigation system in which such other auxiliary means as we found in the radio sign post system are not required, the system is effective in an urban area or other areas subject to radio interference where such radio navigational systems as NAVSTAR GPS (Global Positioning System) and the like do not operate successfully.
